Common name: knobby star coral

General information

The Smooth Star Coral, Solenastrea hyades, is a hardy and adaptable stony coral species that is well-suited for reef aquariums. It is characterized by its smooth, encrusting growth form and star-like corallites, which can vary in color from pale beige to deep brown, often with a contrasting color around the mouth of the polyps.

This coral is not as common in the trade as some other species, but it is appreciated for its resilience and ease of care, making it a good choice for both novice and experienced reef keepers.

Care

Solenastrea hyades is a low-maintenance coral that can thrive in a range of lighting conditions, from moderate to high. It is also tolerant of varying water flow, although moderate flow is recommended to help remove detritus from its surface and to provide nutrients.

Feeding is not strictly necessary for this photosynthetic coral, but it can benefit from occasional feedings of microplankton or other coral foods to promote growth and health.

Symbiosis

While Solenastrea hyades does not have any specific symbiotic relationships that are as well-known or as specific as those of clownfish and anemones, it does host a variety of microorganisms in its mucus and on its surface, which can help protect it from pathogens and aid in nutrient cycling.

Habitat

Solenastrea hyades is found in the Caribbean Sea and the western Atlantic Ocean, typically in shallow waters but it can also be found at depths of up to 40 meters. It often grows on reef slopes and in lagoons, where it contributes to the reef structure and provides habitat for other marine organisms.
